TM scattering by a gap on a circular waveguide

A new method for the analysis of scattering by a circumferential gap on a conducting circular waveguide is presented. The method, based on the Fourier transform and mode‐matching techniques, yields a rapidly‐convergent series solution. Numerical results illustrate the effects of gap width and waveguide radius on radiation and scattering. © 2003 Wiley Periodicals, Inc.
